Product overview
The Makino G7 is a 5-axis horizontal grinding and machining center capable of performing grinding, milling, drilling and tapping in a single setup. Designed for demanding materials and complex geometries, it reduces non-value-added time by combining multiple operations on one machine.

Applications

• Inconel® and other nickel‑based alloy grinding
• Root‑form grinding
• Turbine blade and vane grinding for aerospace

Operational notes
The G7 enables transitions from milling to grinding within the same machine, reducing capital equipment and enabling multiple operations in a single setup to eliminate out‑of‑cut time. It is presented as an effective solution for components made from nickel‑based alloys and for root‑form geometries common in aerospace manufacturing.
